- Clinical Manifestations. True hypersensitivity adverse drug reactions are great imitators of disease and may present with involvement of any organ system, including systemic reactions such as anaphylaxis (Table 2). Drug reactions commonly manifest with dermatologic symptoms caused by the metabolic and immunologic activity of the skin.

Anaphylaxis Anaphylaxis is a type I hypersensitivity reaction. Asthma is another example of a type I reaction, but, whereas asthma is localized to the respiratory region of the body, anaphylaxis has effects throughout the organism. In all type I allergic reactions, sensitization occurs when a substance triggers the immune system to recognize it as a threat to the body.

Rheumatoid Arthritis Hypersensitivity Rheumatoid arthritis hypersensitivity is a state of opposite reaction where the immune system of a body attacks the body cells as an alien substance. Rheumatoid arthritis on the other hand is an autoimmune disease where the joints of the bones are affected.heumatoid arthritis hypersensitivity Type IV. Rheumatoid arthritis hypersensitivity Type IV is also called mediated or delayed hypersensitivity reaction where the reaction takes place on the skin. This is termed so because the reaction takes two to three days to develop.

Clinical ReviewVisceral hypersensitivity in functional disorders of the upper gastrointestinal tract Abstract. Visceral hypersensitivity is now recognised as a major pathophysiological mechanism in functional gastrointestinal disorders of the upper gastrointestinal tract. In patients with non-cardiac chest pain and functional dyspepsia, a high prevalence of visceral hypersensitivity has been indeed observed.

Overview Definition. Pneumonitis (noo-moe-NIE-tis) is a general term that refers to inflammation of lung tissue. Although pneumonia is technically a type of pneumonitis because the infection causes inflammation, most doctors are referring to other causes of lung inflammation when they use the term pneumonitis.. Factors that can cause pneumonitis include exposure to airborne irritants at your job or from your hobbies. In addition, some types of cancer treatments and dozens of drugs can cause pneumonitis. Difficulty breathing — often accompanied by a dry (nonproductive) cough — is the most common symptom of pneumonitis. Specialized tests are necessary to make a diagnosis. Treatment focuses on avoiding irritants and reducing inflammation. 1  Symptoms.
